pos_form_cursor - position a form window cursor
#include <form.h> int pos_form_cursor(FORM *form);
The function pos_form_cursor restores the cursor to the position required for the forms driver to continue processing requests. This is useful after curses routines have been called to do screen-painting in response to a form operation.
This routine returns one of the following: E_OK The routine succeeded. E_BAD_ARGUMENT Routine detected an incorrect or out-of-range argument. E_NOT_POSTED The form has not been posted. E_SYSTEM_ERROR System error occurred (see errno(3)).
These routines emulate the System V forms library. They were not supported on Version 7 or BSD versions.
